Model: UV-2550
NSX: Labomed - Mỹ
Máy quang phổ UV-VIS cơ bản dùng trong các phòng thí nghiệm
Dễ dàng sử dụng, độ chính xác cao, tiết kiệm thời gian và chi phí dùng để phân tích định tính và định lượng trong hóa học, sinh học, y tế, kiểm soát chất lượng, môi trường, quản lý nước, thực phẩm, nông nghiệp,…
* Feature:
This instrument is the realization of a long history of specialized research, design, and manufacture. It is simple in construction and high in performance.
The Spectro may save the reagents and samples by using the optional semi-micro cuvette of 1.5 ml or less to reduce waste. This unit was constructed with high reliability, durability, ease of operation, and maintenance in mind.
Calibration curve can be set up by either measuring or entering up to 10 standards or entering K and B factors directly via the keyboard.
Data can be printed on an optional desktop printer and can be downloaded to a PC through the USB connection.
Up to 10 calibration curves can be stored and edited for user’s convenience.
